' IMPROVEMENT IN FEED-COOKERS.

. Specification forming part of Letters Patent No. 178,796, dated J une 13, 1876; applieationjiled May 13, 1876.

To all whom it may concern:

Be it known that we, IRA B. OLMSTEAD and JOHN W. WILSON, of Ashmore, in the county of Ooles, and in the State of Illinois, have invented certain new and useful Improvements in Feed-Cookers; and do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of our invention consists in the construction and arrangement of a feed-cooker, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation, referring to the annexeddrawing, in which- Figure 1 is a longitudinal vertical section of our feed-cooker. Fig. 2 is a transverse vertical section of the same.

A A represent the sides, and B the bottom, of a box or vat, of any suitable dimensions, placed upon a furnace. G. On top-of the bottom B is a flue,D, running continuously around the interior of the vat, and a suitable distance from the sides A. At the rear end of the fur- .nace 0 there are one or more openings, a, in

pipe.

G represents the inner vat or box, in which the feed to be cooked is placed. This vat rests upon blocks I), laid on the bottom B, and the space between the upper edges of the two vats or boxes is closed at the top by strips I I, as shown.

A suitable quantity of water is poured in the outer vat A B, surrounding the flue D on both sidcs, and one or more passages, d, are made through said flue, on each side of the inner vat G, so as to form a circulation of the a water on both sides of the flue.

In the sides of the inner vat G are made apertures'i i, for the entrance of the steam generated in the outer vat, said inner vat being closed by a lid, J.

It will thus be seen that the food in the inner vat is cooked by the water-bath from underneath and the steam from the top.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination of the vatA B, with openings a a. in the bottom, furnace C, flue D, with passages 61 and smoke-pipe E, interior vat G, with steam-openings 'i, and the lid J, all constructed substantially as and for the purposes herein set forth.
